The ADP2118-EVALZ is an evaluation (demo) board which provides an easy way to evaluate the ADP2118 buck regulator. The ADP2118 is a low quiescent current, synchronous, step-down, dc to dc regulator in a compact 4mm × 4mm LFCSP_WQ package. It uses a current mode, constant frequency pulse width modulation (PWM) control scheme for excellent stability and transient response. Under light loads, the ADP2118 can be configured to operate in pulse frequency modulation (PFM) mode that reduces switching frequency to save power. The ADP2118 requires minimal external parts and provides a high efficiency solution with its integrated power switch, synchronous rectifier, and internal compensation.
